Water left in Black Tank after flushing
Hi. I have a 2013 27RLSWE Cougar. A couple of days into my last trip, I started getting a strong sewer smell in my RV. The black tank indicator only showed 1/3 full. The smell would come and go so I emptied the black tank without flushing. The next day I started getting the smell again. The next day I was leaving so I emptied the tank and flushed it until the water started running clear. However on the way home, we stopped to eat lunch and the trailer smell of sewer again. After I got home, I partially filled the tank and took it to the local dump station and flushed it three times. I looked down the toilet and was able to see clear water. After getting home the water was brown again and the water was about an inch deep. I have not had any smell since then but the water is still brown. I use the recommended chemical in my tank. Is it normal for there to be water left in the tank after flushing. I let it run until it completely stopped. Any advice on the smell problem and whether it is normal for there to be water left after draining would be appreciated. Sorry for the long post.
